To all :whom it may concern Be it known that we,GEoR eE GODLEY and HENRYBIWHITTAKER, citizens of the United States, residing at Philadelphia,inthe county of Philadelphia and State of Pennsyh vania, have inventedcertain new and useful Improvements inSpring-Motors, of which thespring, and arbor on lines 1 1 and 2 2, I ig. 1, i r 5 respectively.Fig. 4 is a perspective'ot' one of the arbors or section of centralshaft?

Our invention relates to that class of springmotors wherein a number ofcages orbarrels, springs, and arbors or shaftsare socombined that themeasure of power obtained from all the springs is equivalent to thatderived from one spring only, while the continuance of the poweracquired is proportionate to the number of springsused, and has for itsobject to diminish the friction between the parts of the motor; toimproved andinexpensh'emeansfor attaching the springs to the arbors andbarrels; to an improved mode of inserting the springs within thebarrels; toinexpensive and 5 durable springs for themotor, whichare'made without b'eingreheated for tempering them; i

to so arranging the springs within the barrels .andconnectingthemthereto and to the arborsthat the strain resulting from their unwindingwill keep the arbors forming the sectional shaft in alignment with eacharbor; to

Fig. 13 is a detail plan, showthe completelubrication of the sectionalshaft, and to simple and inexpensive brake mechanism whereby a cheap,durable, and effective spring-motor is produced.

Our invention accordingly consists of the novel combination,construction, and arrangement of parts, as hereinafter more fullydescribed and claimed.

Referring to the accompanying drawings, A represents the central shaft,composed of sections or arbors a, a, and a the last of which is securedto the base B, having connection with frame or plate B by means of barsor pil-. larsb.

(J 0 represent the cages or motor-barrels, which are alike inconstruction. They are fit-.1 ted. to the arborsfas shown, and turnindependently of each other, as also do the arbors a and a. The latterhave reduced portions or endsdd,respectively,which taper downwardly, orare in the form of an inverted cone having rounded ends 01 The arbors aand a are provided with sockets d which receive the ends d d, asshown,the end (I of arbor a fitting in socket d of arbor c, and the end d! ofthelatter fitting in socket d of arbor a The bearing between the arborsis at the extreme point of the rounded ends (1 thereby reducing thehearing-surfaces between said parts to mini- -8o mum, so as to avoidfriction. The ends 61 (1' being inverted coues,or tapering from abovedownward, and the sockets 01 being cylind'ri cal or parallel, aplay-space, 01 is provided in each socket, so that when the arbors arebent 8 5 out of line said ends move or play in the spaces d? withoutbinding againstthe walls of the sockets d hence the arbors are free torevolve without inducing friction. Said spaces (1* also serve as cupsfor a lubricant, to assure c the proper oiling of the bearings of thearbors,

as hereinafter explained. The arbors a a are each formed with alongitudinal slot, d while the arbor a has two such slots diametricallyarranged, as shown in Figs. 2, 3, and 14. Into these slots the inner orone end of the springs is inserted, as hereinafter fully setforth; and

as twosprings are secured to arborc, it is provided with two slots 01 orone for each spring secured thereto. y The base B has a flange, b,forming a cup or pan, B and the winding-gear E, secured to arbor a andoperated by pinion e-and shaft 6, I f, to secure them to the barrels.The lower is provided with anloil-cup, 6 having an axial opening, a, sothat oil poured into cup e will flow into opening to arbor a, thencedown the same, lubricating its bearingsinthe barrels, andfinally flowsinto the socket d? of arbor a. The oil overflows said socket andtricklesdown the arbor a to'socket d of arbor a andso on until it drips into panB, from which it may be drawn ofi" by means of a stop-cock, (not shownin the drawings;) or it may be dipped out of said pan or otherwiseremoved therefrom.

The cages or motor-barrels O O are each designed to contain two springs,F- F, andhave. therefore two apartments, 0 c, with top, intermediate,and bottom plates, 0", c and a, respectively, with bearin gs or openingsc for the central shaft or arbors. Said openings are formed with roundedor feather edges 0, so as to present as small a bearing-surface to thearbors as possible, and thereby diminish the friction. The plates 0 ,0and c are connected together by posts g,.g, and 9 The postsg are intheform of pins or rods provided with shouldersg", loosely fitting inopenings. 9 in said plates, so as to be removable therefrom, and whenthey are withdrawn from the'barrels extended lateral openings G areformed therein, as shown in Fig. 8, for purposes to be more fullyexplained. The posts g" are provided with vertical recesses. or slots 9for the recep- "tion of the outside ends of the springs, and

with openings 9", for the passage of pins or bars 35 f Said describedparts of the barrels, save the pins 9, are all'cast or. formed in. onepiece, or are integral with each other; hence the barrelsare easily andcheaply made, and all expensive fitting of parts is avoided.

' The springs F are formed ofcrucible caststeel, so that when theribbons for the springs are rolled and coiled into springs the latter donot have to be reheated to temper them, they being tempered in the actof rolling the ribbons; hence we dispense with all reheating processesand other expensive manipulations forgiving the springsan even temperthrough out their entirelength. The use of such crucible-steel springsis an important part of our invention, as We are thereby able to obtainsprings of great length which have corresponding or equal elasticityfrom end to end. They therefore can be made at a greatly-reducedcost,and are far more durable than the springs heretofore used. While wedeemsuch springs preferable for our invention, we do notlimit and the pinsfpassed through openingsg and inserted into the loops or openings of theends to standard K.

extremities of the pins f rest upon the bottom of the recesses 9 asplainly shown in Fig. 1 The respective arbor or arbors are then passedthrough the bearings 0 as represented by dotted lines in said figure,and as they enter the barrels the inner ends,f, of the springs passintothe slots d and are thereby secured or attached to said arbors,whereupon the pins g are inserted in their places.

Y The posts 9 of the barrels being located on opposite sides thereof,the two springs in each barrel" have reverse or opposite connectionstherewith, as plainly shown in Figs. 2 and 3. Consequently when theyunwind each such spring exerts a strain upon opposite sides of thearbors or sectionalsh aft, and as such strain or torsional action of onespring is opposedto that of the other, they neutralizeeach other, andthe parts of the sectional shaft are thereby maintained in duealignment. with one, an-

other, and friction is avoided, while heretofore such strain has fallenon one side of said shaft, bending it out of line, producing unduefriction and causing a Waste of spring-power.

H represents a drum or casing for the motor, composed of sections 71..h. Each section consists. of two semi-cylindrical parts, h h,

preferably of sheet metal, like steel or springbrass: or suitablematerial, hinged at W, and having a-locking pinor catch, h. The casin gbeing in sections, one or bothv sections maybe removed, asidesired, toobtain access tothe motor. Upon the arbor a is a brake-wheel, I, and a41 represent the brake-shoes, pivoted at i L is a bar having a doublewedge-shaped end, Z, fitting in the openings i i in or between thebrake-shoes,which are provided with a spring, M, for clutching orbrakingthem on the wheel I. When the rod or bar L is drawn to the right,its wedges l draw or move the shoes iiapartand release them from thewheel I. The bar L may be operated by a treadle or hand-lever, asdesired. So, too, a train of gearing may be attached to or'monnted onthe shafts a and k to obtain the desired speed. The springs are wound upby turning the shaft 6, a suitable ratchet being 'used in connectionwith the device, as in other spring-motors.

A motor so constructed can be made at a comparatively low cost. Thefrictionbeing greatly diminished, the full effective power'of thesprings is obtained for the performance of the work, and but a smallportionof it is lost,

while in spring-motors as heretoforeconstruot ed a greater portion ofthe spring-power .is wasted in overcoming the friction.

. It will be noticed that the springs are. connected to thebarrelsand-arbors without'riv eting, screwing, or otherpermanentfastening. Consequently when broken they can be readily removed from themotor and replaced by new ones.

lugsmmay be formedthereon, and. the ends of the spring be formed withloops m, to em- Instead of the slots in the arbors and barrels,

brace said'lugs, as Tshownin Figs. 6 and 7. So, too, saidslots in thearbor, 860., instead of betapering, as shown in Fig; 13, to receive thebent square endsof the'spring.

We have shown two barrels containing two springs; but we do not wish tobe understood as confining our invention thereto, as more than twobarrels may'be used; or a single barrel with one spring or othermodifications may be substituted. So, too, while we have shown a centralsectional shaft withslots or lugs for securing the springs thereto, wedo not limit our improvements to the sectional shaft, as it may be oneshaft throughout, or a rod surrounded by sleeves, to which the springsmay be secured. Again, the tapering ends 01 of the arbors maybedispensed with and a ball and-socket bearing, 0, substituted therefor,as shown in Fig. 10. If desired, the slots d in the arbors maybe formedas shown in Fig. 14.
